hello everybody
new user here , found some post on this forum regarding KD-261 modding ,and tried a bit myself..

so the problem is , I removed the preamp board and connected a 100k pot (variable shunt attenuator according to Gregs mod)
and have a little constant buzz now , and have no idea what is it related to...

I have connected it like this https://lh4.googleusercontent.com/-7...da%2520mod.JPG

and everything seems to work allright except that little annoying buzz .

would be glad if someone could shed some light on it as im pretty new to this...
